I've just been told I need a new 8AT gearbox for my F30 Sport. The car has less than 20000 miles on and about 5000 miles ago developed a really annoying loud whistle whilst going in reverse. BMW have booked me in to swap it out next week. Was just wondering if anyone else has had a similar issue???

That's interesting, my gearbox has only covered 9K miles since July last year but for the last 1,500-2,000 miles I've noticed a distinct whine in reverse that wasn't there in the early days. Not bad, but may have to watch out for it getting worse.

Hey Rob did it start with a light whistle/ whine... mine is on 7k and I already have a noticeable noise in reverse...thinking I need to take it in

Hi all, just to give you an update. Mines got progressively worse over the last 5k or so. It's now started to jolt forward when I come to a stop, like its having trouble selecting a gear. It's booked in for Monday and it looks like just in time too.
